It was back in December 2015, that Shark Tank star and Dallas Mavericks owner Mark Cuban called Donald Trump — with whom he’s claimed friendship over the years — a “never ending source of Headline Porn.” Cuban claimed Trump’s ability to create salacious sound bites meant he was easily digested on social media and became the central focus of political conversations — even by mainstream media.

Now, Cuban has said Trump is easy to tease because of his tendency to take himself too seriously. In a roundtable discussion of reality television stars hosted by The Hollywood Reporter, Cuban weighed in on Trump’s candidacy and his own Twitter spats with the real estate mogul and the man who could be the next president.

“I’ve gotten into battles with Donald on Twitter, and other places, and on TV and all that stuff. He’s just so easy to f*** with, right? He’s got no sense of humility or humor, no humor whatsoever. That’s what makes him so easy to mess with.”

Cuban has been vocal about his Trump-related opinions in the past several months, saying at one point he would “probably” vote for Hillary Clinton because she has a more detailed economic plan. He reiterated in the Hollywood Reporter session his view that Trump’s campaign is reminiscent of a 1990s sitcom.

Cuban has also leveled serious accusations against Trump’s ability to be president, saying his lack of knowledge would make him completely dependent on his advisors. He also questioned Trump’s net worth, implying the brash businessman is not as rich as he claims to be, according to CBS News.

But Cuban and Trump share a propensity to say things that get them into trouble. In that December, 2015, blog post, Cuban discussed his own history of being fined by the NBA for his comments and the back-and-forth he had with media outlets looking for sensational headlines. Last month, The Washington Post carried a Texas Tribune-penned quiz entitled: “Who said it: Donald Trump or Mark Cuban?” Readers who think they know either man well might find the quiz trickier than anticipated.

Cuban confirmed to THR that he has given a political run of his own some thought, a change from several years ago when he didn’t think it was a possibility. He is weighing his options according to whether or not it would be the best role for him to have some influence.

“If you were to ask me six years ago, four years ago, I would have said, ‘H*** no.’ But given what’s going on, and given kind of how people feel about everything… you know, I’m the luckiest guy in the world, and I’m in a position where if I wanted to invest in myself to do something, I could. If I wanted to do something to get people behind me, I could. It’s just a question of whether I can have the greatest impact there, or doing what I’m doing.”

Cuban said last month that he would be interested in being either candidate’s VP pick — but not without conditions. According to CBS News, he’d want to see Clinton move closer to the center and would insist on a sit down with Trump to get an in-depth understanding of the issues and develop solutions before being on his ticket.

Mark Cuban is a lifelong entrepreneur whose first business was selling garbage bags at age 12. He sold a business for $6 million at the age of 32 in 1990. He and his business partner sold Broadcast.com in 1999 for $6 billion, according to Biography.
